<br><br><font size="4"><u>JSBSim</u></font>&nbsp&nbsp
is an open-source project created by John Berndt (<a href="https://sourceforge.net/u/jberndt">sourceforge...jberndt</a>) to model aerospace vehicles.  The project can be found at SourceForge <a href="https://sourceforge.net/projects/jsbsim/">here</a> and at GitHub <a href="https://github.com/JSBSim-Team/jsbsim">here</a>.

is the Portable game LIBrary, built by Steve Baker (<a href="https://sourceforge.net/u/sjbaker">sourceforge...sjbaker</a>).  The project can be found at SourceForge <a href="https://sourceforge.net/projects/plib/">here</a>.  QtJSBSim uses the joystick tools from PLIB.


<a name="qflightinstruments"></a>
<br><br><br><font size="4"><u>QFlightInstruments</u></font>&nbsp&nbsp
is an open-source project created by Marek Cel (<a href="https://sourceforge.net/u/mcel">sourceforge...mcel</a>) to model aircraft flight instruments using Qt and SVG graphics.  The project is hosted at SourceForge <a href="https://sourceforge.net/projects/qfi/">here</a>.
  QtJSBSim uses the Primary Flight Display from the QFlightInstruments project.


<a name="flightgear"></a>
<br><br><br><font size="4"><u>FlightGear</u></font>&nbsp&nbsp
is an open-source flight simulation framework project created by Curt Olson (<a href="https://sourceforge.net/u/curt">sourceforge...curt</a>).  The project is hosted at SourceForge <a href="https://sourceforge.net/projects/flightgear/">here</a>.
  QtJSBSim can run as an "external FDM" for FlightGear, sending flight dynamics data to FlightGear, which can then be used as a visualizer (and much more!).

<br><br><font size="4"><u>Downstream projects</u></font>&nbsp&nbsp<br>
are projects that use some or all of QtJSBSim in combination with other projects.  Here is one project that I know of by Elias Tarasov that combines QtJSBSim with FlightGear, his own autopilot system, and a quad-rotor model: <a href="http://imgur.com/8eSSx0K">screen capture</a>
